GEARING.

Specification of Letters Patent.

Patented Dec. 3, 1918.

Application filed January 17, 1918. Serial No. 212,268.

To all whom it may concern Be it known that I, WILLIAM IV. HUDSON, a citizen of the United States, and a resident of Salt Lake (Jity, in the county of Salt Lakeand State of Utah, have invented certain new and useful Improvements in Gearings, of which the following is a spec-1- fication.

ing, and has for its object to provide mechanism ot' the character specified especially adapted for comn-cting a dri ving shaft with a gear ring of the chara ter used in ball mill or rotary kilus. in ore grinding and cement work.

In the drawings:

Figure l is a front view of the improved gearing, with parts in section;

Fig. 2 is a section on the line 2-2 of Fig. l.

In the present embodiment of tion a driving shaft 1 is the invenjournaled in fixed support or base 3, and the said hearings have lubricating means in the form of oil cups 4, which lead the oil to the shaft, a bushing 5 being arranged between the shaft and each bearing. Stop collars 6 are provided at the the shaft, and the said shaft is adapted to be connected to a suitable motor flexible connection.

This shaft. 1 is provided with an annular series of tooth forming a pinion 7 between the bearings, and the pinion meshes with a series 8 of internal gear te th in a hollow pinion 9. This pinion 9 is a cylindrical body, and the teeth thereof mesh with the teeth of the gear ring 10 on the drum or kiln for rotating the same. The pinion 9 has cylindrical extensions 11 at its ends, which are co-axial with the pinion, and these extensions are received within sectional bearings 12 supported by the base and rigid therewith, the arrangement being such that the pinion 9 rotates on an axis eccentric to by means of a the Shan as shown, so that My invention is an improvement in gearends of A bushing 13 is arranged between each bearing 12 and the adjacent extension 11, and oil cups 14 are provided for lubricating the hearing. The ends of the pinion 9 are closed by plates 15, which are secured to the ends of the bearings 12, as shown at the left of Fig. l. The bearings 2 are also sectional,

the parts may be easily assembled and disassembled.

In operation, when the shaft 1 is rotated, the pinion 9 will be rotated, because of the engagement of'the teeth 7 with the internal teeth 8 of the pinion, and the pinion 9 will in turn rotate the gear ring 1001' other elementto which it is connected.

I claim:

-1. A gearing com rising a support, bearings at the ends of t 1e support, a shaft journaled in the bearings and provided between the"- bearings with a rigid pinion, a ring shaped driving pinion through which the shaft passes and ha ring internal gear teeth for i'neshing with'lhe teeth of t e pinion of the shaft, the support having bearing rings at the ends of the driving pinion, and the driving pinion having reduced cylindrical bearing'extensions engaging the rings, and a means for lubricating each of the bearings.

A gearing comprising a hollow driving pinion having an internal gear, a shaft passing through the pinion amlliaving a pinion engaging the teeth of the internal gear, fixed hearings in which the shaft is journalcd, and fixed bearings for the pinion, said bearings for the pinion comprising rings, the driving pin on having cylindrical eX- tensions co-axial with the pinion and extending into the rings. r

A gearing comprising a ring having internal and external gear teeth, fixedbeariugs for the ring, and a shaft passing eccentrically through ion engaging the teeth of the-internal gear.
